C necessary before C++?

[WingedPanther]

Here's an example of how C++ can help you in ways C can't:

#include <gmpxx.h>
#include <iostream>
using std::cout;
using std::cin;

int main()
{
  int num;
  cout<<"Pick the number you want to raise to a factorial: ";
  cin<<num;
  mpz_class fact=1;
  for(int j=1;j<=num;j++)
    fact*=j;
  cout<<num<<"! = "<<fact<<"\n";
  return 0;
}

It uses the GNU Multi-Precision library, which provides a class for arbitrarily large "integers". As a result, it is object oriented. The class is a wrapper for a collection of C functions, so you can use this library with C as well. However, just looking at the code, it appears to be a simple procedural program with a funny data type. This is the power of C++. You can create classes that simply get out of your way and let you work without thinking too much about them. The C version of this program, using the same library, is much more complicated and imposes more responsibility on the user.

Interesting elaboration, Winged. So is this topic going wider? Perhaps we could ask: should he learn assembler before C before C++ before C#?

[WingedPanther]

I'd say that C# is more of an aside to the C/C++ debate. C# borrows more from Java than from C++, though Java of course takes a lot of ideas from C++.

Although C++ is very different from both in my opinion.

Yea, in all universities they teach C before C++ for people know the differences between programming paradigms.

Be careful with your use of universal quantification. I am in my fourth year of university, and I've yet to learn C.

In our univercity C++ is studied at the first semester but education program don't give sufficient attention for C, so some students don't understand differents between this languages I think it's wrong

It isn't really necessary to teach C for u to understand the differences between two paradigms, there are many procedural languages like C.

well, that's really very strange, what languages had you learned in university?

[Chinmoy]

definitely not. They are two different things. People are often made into believing that learning c helps before c++. I would say, do not waste your time, go for c++ straight and then come back to C just to learn the diferences in usage, there are only a few. read here :: Differences between c and c++ | TECHARRAZ

No C is not necessary before C++. They are two different languages, you dont need to know C before learning C++
